Fix NULL alarm_timer pointer at exit
This fixes a SIGSEGV error on qemu exit. Here is the valgrind output related to this error ==3648== Process terminating with default action of signal 11 (SIGSEGV) ==3648== Access not within mapped region at address 0x8 ==3648== at 0x40636B: host_alarm_handler (vl.c:1345) ==3648== by 0x52D807F: (within /lib/libpthread-2.9.so) ==3648== by 0x5C0A12E: tcsetattr (in /lib/libc-2.9.so) ==3648== by 0x4DD601: term_exit (qemu-char.c:700) ==3648== by 0x5B636EC: exit (in /lib/libc-2.9.so) ==3648== by 0x5B4B5AC: (below main) (in /lib/libc-2.9.so) This simple fix check for a valid pointer as host_alarm_handler is also called after alarm_timer is released in the exit path.
